osKAB. JUNGHANS, or `sonaalvrERG7 Gum/Alva PLAYING CLOCK.

Application Vliled. November To all whom- ?I fmcfe/ concern.' y

Be it known that l, OsKAn JUNGHANS, a citizen of the German Republic, residing at Schramberg, Germany, have invented Certain new` and useful Improvements in Playing` Clocks, of which the following is a specilication. .i

My invention relates to an improved clock which is intended to be used for puffing or advertising purposes -in showwindows oras a toy for childrenorthe like, and with this aim in view the clock is combined with a game of dice and con-1 structed and arranged in a manner that the dice are periodically or intermittently thrown down mechanically, that is to say,

through the agency of the clock-work, and the number of points thrown will vary just as if the game lis played'manually in the usual way. Y

Among the principal objects which my invention `has in view are: to'V provide a container for the dice Vwhich towards the side where the `dial is located, has a show opening for the thrown dice toi-be looked atso that the number of points thrown each timewillbe readily visible'to the spectators, to provide, in order to increase the effect or the attractiveness of the playing clock, a member in the shape of a human arm of reduced size which has a dice-box in its hand,l said member or varm being mechanically connected with the clockworkto exercise a throwing movement each time thedice are thrown and appear in front of the show opening, so that the illusion `of the, trick will be complete and'the spectators. will get the impression of a reallyplaying clock; to provide, inorder to firmly estab lish such illusion, the said movable arm, as a part of the picture -ofa person suitablyapplied on an appropriate part of the clock preferably on the dial thereof. i

One embodiment of my invention is disclosed in the structure diagrammatically, illustrated in the accompanying dra-wings,

in which like characters of'`reference:'denote corresponding parts in the 4'several views and in which t Figure l is a front view of the clock with the dial and other parts omitted in order to afford a clear view ofthe mechanismf .or 'stop lirmly lconnected .with the vertltherehehind,

Figure `2 is a vvertical section and Figure 3 is a view similar toFigure l with the upper Apart broken olf andwwith 14, 1924. serial No. 749,972.

a suitable light material, are-free to move or, properly speaking, be moved therein. The ,glass or window Z is nottransparent throughout but the, upper part thereof and more than'half of the totalj` face of `the glass is covered with any suitable coating impervious to light-so 'that'only a` small area will be transparent at the lower end or bottom of the container for the exhibition of the dice.4 Preferably the coating which renders thelarger upper portion of the glass impervious j'to light, may be in continuity and conformity with the usual Or required painting tof-be-'given to vthe outer face of the dial for ornamental or other purposes.

Pivotally connected tov the front vertical plate of the clock-work is an oscillating bent lever e in the shape of a human arm which normally depends in the position shown in Figure l. The lower end of the arm is shaped to form a hand holding a dice-box as' will be clearly seen in Figure l. Of course, the dice-boxeis a flat member only for an illusory purpose and adapted to lie in 'front of the dice while the latterare moved in clockwise `direction `by a mecha* nism to be described hereinafter.

Pivot'ed to theinner Vfaceof the disk 5,

at Q,isa shovelfor board f and ay pin 7L of the shovel or board f projects through a slot in the diskk bto'and `beyond the rear face thereof as will be clearly seenin Figure 2. A flat spring provided on the rear face of the disk engaging, with its free end, thel pin 71., in order to maintain the shovel orboard in Figure y 1.

The movable lever or arm` eis maintained iniits depending position shown in Figure 1V bykilf bell-crankv lever j, thesone arml of said lever engaging with a stationary Vstud cal plate of the clock-work or time mechaf inthe position illustrated e nism` while the other arm thereof abuts againsta-v stud or pin m, y provided on the As a result ot the described action of fthe bent lever e in the vicinity of the pivot thereof, i

The operation of the described device is as follows:

Figure 1 illustrates the dice and the other parts of the device in the position subsequent to a throw. The disk b forming the rear wall of the container d rotates continuously in clockwise direction as indicated by an arrow thus causing the shovel or board f to move or shift thefdice in clockwise direction over the narrow cylindrical wall ofthe container. The movement of the dice can be viewed by the spectators owing to the transparent area. at the bottom of the glass or window Z, butfas soon as the' dice reach a point coinciding with the rim of the dicebox at the lowerend of the bent lever e', they will in reality disappear behind the coated part of the glass or window Z, While to the spectators the illusion is created as if the dice have been thrown and returnedA into the dice-box at the lower end of the lever e, as will be readily understood on inspection of Figure 1.

On the continued revolution of the second arbor or shaft a with the disk b'the dice are lifted by the shovel or board f, but this cannot be viewed by the spectators on account of the upper part of the glassl or window Z being impervious to light; at the same time the pin h. of the shovel or board f comes into engagement with the extremity of the lower arm of the bell-crank lever y', while the upper arm of the lever y' is inpermanent engagement with the pin mot the lever or arm e, so that on the further continued revolution of the' disk o and the shovel or board fthe lever will be turned or oscillated about itsl pivot mrwhereby the lever or arm e is moved from the kposition shown in Figure l to the positionv illustrated in Figure 3. As soon, how-ever, as the upper arm of the lever j' engages the pivot o ot the lever or arm e and is arrested thereby which already occurs before the parts have adopted the position shown in Figure 3, the spring z' yields and Jthe shovel or board 7 turns about the' ping mo'vingwith the disk o' incessantly in clockwise direction-'until the parts are Ain the position illust-rated in Figure 3 whereupon the pin LA at a' predetermined angular position of the shovel or board releases the lower arm of the-bellcrank lever j. Immediately upon such release the tension of the spring al acts to project the shovel or board f back into its' previous Vrelative position shown in dotted lines in Figure 3so that the "pinl tagain engages -in the bore-end of the slot ofthe disk 7).

spring the dice are thrown forwards in the direction ofthe arrows and drop to thev their impacts on the wall of the container and the spherical rglass Z of the disk change their positions so that also the number ot' points thrown will be diiierent from the number previously exhibited, just as in a regular dice game.

As soon as the pin h releases the lever y', as i described, both the lever j and the lever or arm e will be free to return into their normal position of rest shown in Figure l, owing to their weight or the action of gravity, and the'lever y' then will again engage and rest upon the stud or stop 7c. The uninterrupted revolution of the disk b together with the shovel or board f causes the play to continue again and again as long as the clock is wound up. I i

yI have not attempted to explain all ot the minute details of the construction of the clock, for it will be understood by those to vwhom this specification is addressed that the parts will necessarily be of conventional' size and relationship and will be properly mounted and supported in accordance with the tenets of mechanical construction; nor have I attempted to illustrate the parts in their exact sizes and dimensions as some parts are conventionally shown. I iind that the embodiment described and shown is preferable and most eiiicient but realizing that certain; conditions will necessarily vary in concurrence `with the adoption of my device, I desire to emphasize the fact that various minor changes in the details of construction and in the proportion of parts may be resorted to when required or'desired, without sacrificing any of the advantages of my invention as defined in the appended claims. y
